Biological Evidence

Biological Evidence Biological evidence is evidence that can be tested through DNA mapping and other profiling methods. Each specific type of evidence, whether it be saliva sample or semen sample, needs special techniques in acquiring and preserving in order to avoid cross contamination. These types of evidences are cross examined with a suspected person to either exclude them or prosecute them for the crime. In this paper I will discuss the different types of evidence and how it is preserved when it is obtained from a crime scene. Different Types of Evidence A forensic team might encounter different types of evidence at a crime scene. It is on the team to…show more content…

Making sure that these tools are sterile is a top priority for a forensic specialist. Cross contamination is one of the incidents that can occur during the transport of evidence. It can also occur when the evidence is repackaged and not done in the correct manner. Other kinds of cross contamination may occur, for example: “For instance, the clothing of the suspect should never be packaged or handled in the same room as that of the victim and the investigators should be able to prove this procedure was followed.” [“Cross Contamination." World of Forensic Science. 2005. Retrieved December 20, 2014 from Encyclopedia.com: http:// www.encyclopedia.com/doc/1G2-3448300163.html]. It is important to maintain proper control of evidence since prosecutors look at that to use for the benefit of the case. They can argue that the evidence has been tampered with, making it worthless in a case. Precautions DNA samples obtained from a crime scene is very important during an investigation. In order to obtain the highest quality of evidence that can be used in a case, certain precautions must be taken. The typical gloves and masks are always important while collecting any type of liquid-form evidence. Communication becomes key in the handling of all evidence. Especially the first investigator that arrives at the crime scene. Each member of the forensics team and investigators need to collaborate each step of the way.

cordoned perimeter. Without this first step, evidence found at the scene can be compromised or worse destroyed which could result in possibly ruining any opportunity to create a strong case to arrest and convict a suspect. Once secured, the crime scene can be processed.
There is a basic protocol that all investigators follow and even though each crime scene is different with a vast array of circumstances the basic procedures remain the same.

meaning split' and phren meaning mind'. DSM IV (1994) estimate that the occurrence rate of schizophrenia ranges from 0.2%-2.0% worldwide. There are two main explanations of schizophrenia: the biological explanations and the psychological explanations. In this essay I will critically consider the biological explanations. These include genetics, neurochemistry, brain structure and evolution.
Genetic factors of schizophrenia can be explained using studies on twins and studies on family history.….

The biological approach asserts that something in our biology is the fundamental cause of dysfunctional behaviour which could be a genetic cause or a malfunction of brain structures. Although it is seen as the most common explanation for schizophrenia due to the use of drug therapy, it would be deterministic and reductionist to explain schizophrenia only with the biological approach since there are other numerous factors such as the ones related to the cognitive explanation or other environmental….

Slowing the Biological Clock
The biological clock is an organism’s rhythm that controls the cycle of behaviors that occur on a daily basis. Slowing the biological clock is in reference to the cells that are constantly changing in an individual’s body. A person should take care of his or her body at a young age because the effects of the care will have outcomes as the person ages. There are several contributing….

Who funds the making of chemical or biological weapons? The answer is many people. However the government is the main source of money. For example, they make labs built to find defenses against new chemical or biological weapons. The catch is that in order to find new defenses, they must first build new weapons. That brings us to terrorists. Government officials make the….

2) The four (4) statements that appear in “Practice….

Crime theories are still in a development stage; it is an evolutionary process that continues to this day. Crime is still a complex and misunderstood phenomenon with no concrete evidence when it comes to human behavior. Throughout time there have been endless amounts of crime theories, few of which revolve around biological explanations. We have Cesare Lombroso and the Positive School who thought that criminals were genetically different from the rest of the general population, that they were biologically….
